Comprehensive performance analysis of flexible asynchronous AC link under various unbalanced grid voltage conditions

A flexible asynchronous AC link (FASAL) system is a technology that interconnects two power networks operating at the same or different frequencies. The FASAL newly developed technology; therefore, it requires thorough investigation under unbalanced grid voltage conditions for better behavioral understanding and appropriate future controller design. In this paper, analyzed various symmetrical asymmetrical conditions. Moreover, performance of back-to-back source converter (VSC) based HVDC also to establish its comparison with VSC-HVDC systems are modeled in PSCAD/EMTDC software environment. simulation results illustrate transient as well steady-state Furthermore, reduction receiving end side lesser system. For example, 10% sag contributes only 15% dip system, whereas reports 30% condition.
